i think the court of public poin opinion is going to kerry the day and reestablish the standards because people in government and the state department and defense department pay attention to what voters know. voters go see movies and read books. as we understand more about the story, i believe the answer simple. there is no passage of time that changes the character of theft. if we can determine a work of art is stolen, it shouldn't matter it took 60 years to find it out. it should be returned. >> host: if you cannot get through on the phone lines, contact us on twitter #booktv is the tag. and from our facebook page is this question: while we all agree stolen art should be returned. how fast back in history should we go? the peacock throne returned to india? also how do you how do you respond to the argument that taking the rosetta stone protected it from local thieves or neglect. >> guest: that is a great question. it is slippery slope when we go back before world war ii. we can be proud of the works of art here have been donated or acquired through funds donated to the national gallery
